Question

Quizplus · Accepted Answer

Approximately 33 percent of solar radiation is reflected back into space by Earth's atmosphere and surface. This is known as the planet's albedo. The majority of this reflection comes from clouds, but also includes other reflective surfaces such as ice, snow, and water. The remaining 67 percent is absorbed by the Earth's atmosphere and surface, leading to warming of the planet.
